I have recently built the function which converts all special characters from a given string, but excapes all html tags and if there are already any valid special characters - it simply ignores them.

Here it is:

function encodeHTML($string) {

$pattern = '<([a-zA-Z0-9\.\, "\'_\/\-\+~=;:\(\)?&#%![\]@]+)>';

// put text only, devided by html tags into array
$textMatches = preg_split('/' . $pattern . '/', $string);
// array for sanitised output
$textSanitised = array();
			
foreach($textMatches as $key => $value) {

$textSanitised[$key] = htmlentities(html_entity_decode($value, ENT_QUOTES, 'UTF-8'), ENT_QUOTES, 'UTF-8');

}
			
foreach($textMatches as $key => $value) {
$string = str_replace($value, $textSanitised[$key], $string);
}
			
return $string;

}
